Reloader 17/19 for 210/225 gr weights
In the limited amount of loads I have tried R16 it loads really close to R17 sometimes duplicating the same charge and velocity. R16 is also useful anytime a 4350 powder would work. From the 25-06 to the 275 H&H it has applications and seems versatile. Starting loads for R17 are a good place to begin.
